Age-Related Macular Degeneration
Age-related macular degeneration (AMD) is a leading cause of severe visual loss among the elderly. AMD patients are tormented by progressive central blurring/loss of vision and have limited therapeutic options to date. Drusen accumulation causing retinal pigment epithelial (RPE) cell damage is the hallmark of AMD pathogenesis, in which oxidative stress and inflammation are the well-known molecular mechanisms.

Stingless Bee Honey as Antidepressant
Depression is a debilitating psychiatric disorder impacting an individual’s quality of life. Conventional treatments include tricyclic antidepressants (TCAs), norepinephrine–dopamine reuptake inhibitors (NDRIs), monoamine oxidase inhibitors (MAOIs), and serotonin reuptake inhibitors (SSRIs). Despite numerous pharmacological strategies utilising conventional drugs, the discovery of alternative medicines from natural products is a must for safer and beneficial brain supplement. Stingless bee honey (SBH) has been proven to contain a high level of antioxidants compared to other types of honey.

Ensembl Genomes
Ensembl Genomes is a scientific project to provide genome-scale data from non-vertebrate species. The project is run by the European Bioinformatics Institute, and was launched in 2009 using the Ensembl technology. The main objective of the Ensembl Genomes database is to complement the main Ensembl database by introducing five additional web pages to include genome data for bacteria, fungi, invertebrate metazoa, plants, and protists. For each of the domains, the Ensembl tools are available for manipulation, analysis and visualization of genome data. Most Ensembl Genomes data is stored in MySQL relational databases and can be accessed by the Ensembl Perl API, virtual machines or online. Ensembl Genomes is an open project, and most of the code, tools, and data are available to the public. Ensembl and Ensembl Genomes software uses a "permissive Apache-style open-source" license, making it free for all users.

MOTS-c Functionally Prevents Metabolic Disorders
Mitochondrial-derived peptides are a family of peptides encoded by short open reading frames in the mitochondrial genome, which have regulatory effects on mitochondrial functions, gene expression, and metabolic homeostasis of the body. As a new member of the mitochondrial-derived peptide family, mitochondrial open reading frame of the 12S rRNA-c (MOTS-c) is regarding a peptide hormone that could reduce insulin resistance, prevent obesity, improve muscle function, promote bone metabolism, enhance immune regulation, and postpone aging. MOTS-c plays these physiological functions mainly through activating the AICAR-AMPK signaling pathways by disrupting the folate-methionine cycle in cells.

Antioxidant-Based Therapies in Male Infertility
Under physiological conditions, reactive oxygen species (ROS) play pivotal roles in various processes of human spermatozoa. Indeed, semen requires the intervention of ROS to accomplish different stages of its maturation. However, ROS overproduction is a well-documented phenomenon occurring in the semen of infertile males, potentially causing permanent oxidative damages to a vast number of biological molecules (proteins, nucleic acids, polyunsaturated fatty acids of biological membrane lipids), negatively affecting the functionality and vitality of spermatozoa. ROS overproduction may concomitantly occur to the excess generation of reactive nitrogen species (RNS), leading to oxidative/nitrosative stress and frequently encountered in various human pathologies. Under different conditions of male infertility, very frequently accompanied by morpho-functional anomalies in the sperm analysis, several studies have provided evidence for clear biochemical signs of damages to biomolecules caused by oxidative/nitrosative stress. In the last decades, various studies aimed to verify whether antioxidant-based therapies may be beneficial to treat male infertility have been carried out.

Social Image of Nursing
Nursing is a discipline on which stereotypes have persisted throughout its history, considering itself a feminine profession and subordinated to the medical figure, without its own field of competence. All this leads to an image of the Nursing Profession that moves away from reality, constituting a real, relevant and high-impact problem that prevents professional expansion, and that has a direct impact on social trust, the allocation of resources and quality of care, as well as wages and professional satisfaction.

MRCPsych
MRCPsych (Member of the Royal College of Psychiatrists) is a postnominal qualification awarded to physicians who have completed the prescribed training requirements and membership examinations mandated by the Royal College of Psychiatrists. Candidates must be registered with the GMC or a recognized medical board in their own country and should have undergone three years of training. Although initially a two-part exam, the examination has undergone a radical change in the past few years, notably in terms of focus and structure. Although originally a two-part exam, the current examination is 3 parts, consisting of 2 written papers (Paper A and Paper B) and a clinical exam (CASC). Paper A focuses on Neuroscience, Pharmacology, Psychology and theory, while Paper B focuses on Current Clinical Practice & Evidence within General Adult and the various subspecialties of Psychiatry, Epidemiology, Statistics, Critical Appraisal and Psychotherapy The Royal college of psychiatrists has announced the change of format of the CASC exam changes for the exam in January 2018. The 4 linked stations in the morning session will now become 8 single stations with 4 minute to read and 7 minutes to complete the task. 6 of these will be patient management focus and the other 2 history taking. The other 8 single stations remain the same format 90 s to read and 7 minutes for the exam.

Obesity Pathogenesis: Role of CNS
Obesity is a serious health problem because it is rapidly expanding and at the origin of intense morbidity and mortality, especially due to the diabetes that accompanies it.It is not possible to cure it effectively, except with bariatric surgery, which is highly invasive and with many limitations. Trying to understand the mechanism of this efficacy, the studies point towards the correction of the altered control by the CNS of food intake and energy homeostasis. At the biomolecular level, the possibility of a pharmacological therapy based on the modulation of the post-synaptic receptors of glutamate, in particular of the NMDA GluN2A and GluN2B subunits, is foreseen.

Ultrasound Contrast Agents for Therapy
The blood-brain barrier is the primary obstacle to efficient intracerebral drug delivery. Focused ultrasound, in conjunction with microbubbles, is a targeted and non-invasive way to disrupt the blood-brain barrier. Many commercially available ultrasound contrast agents and agents specifically designed for therapeutic purposes have been investigated in ultrasound-mediated blood-brain barrier opening studies. The new generation of sono-sensitive agents, such as liquid-core droplets, can also potentially disrupt the blood-brain barrier after their ultrasound-induced vaporization.

Dermatophytoses
Dermatophytoses affect about 25% of the world population, and the filamentous fungus Trichophyton rubrum is the main causative agent of this group of diseases. Dermatomycoses are caused by pathogenic fungi that generally trigger superficial infections and that feed on keratinized substrates such as skin, hair, and nails. However, there are an increasing number of reports describing dermatophytes that invade deep layers such as the dermis and hypodermis and that can cause deep infections in diabetic and immunocompromised patients, as well as in individuals with immunodeficiency. Despite the high incidence and importance of dermatophytes in clinical mycology, the diagnosis of this type of infection is not always accurate. The conventional methods most commonly used for mycological diagnosis are based on the identification of microbiological and biochemical features.
